As the Big Apple gets pummeled by a forceful blizzard, Justin Bieber’s fans proved to be true Beliebers in anticipation of his upcoming “Saturday Night Live” gig – even if they’re getting hypothermia in the process.

Bieber will host and be the musical guest for “SNL” tomorrow night and frozen fans have been camping outside of 30 Rock since yesterday to get standby tickets, BuzzFeed reports. (By the way, a standby ticket does not guarantee entry to the show.)

“Everyone keeps saying we rock or how cute we are for waiting for standby tickets from tonight til sat moring #BeliebersGoHard #BieberOnSNL,” wrote one brave fan on Twitter.

Some fans got there as early as yesterday afternoon, which means they’ve already spent one night sleeping on the freezing sidewalk. Others joined during the day as snow and rain battered the city.

Undaunted, a fan tweeted, “@justinbieber it started snowing at 6am!! At least outside 30 rock where we are waiting for you! #snl #hypothermia”

A source from NBCUniversal told BuzzFeed that they will be passing out standby tickets at 11 p.m. tonight instead of the usual time at 7 a.m. Saturday.

Meanwhile, Bieber battled through a bout of suspected food poisoning and threw up during rehearsals, according to his manager Scooter Braun. “Great first day at SNL with @justinbieber …so he vomited a little bit. Guys a trooper,” Braun tweeted.

On Wednesday, Bieber was back on his feet, even if he’s a little nervous. He tweeted, “Think i had food poisoning yesterday. rested up… am i nervous? yep. #outofmyelement but im excited.”

UPDATE: A HuffPo writer tweeted that “SNL” will start giving tickets out at 6 p.m. until 11 p.m. and are handing out soup to the standby line.
